Embodiment 1

[0046] (1) Preparation before forming a net

[0047] The raw material is a mixture of polyester and viscose. The specification of polyester is 4D×92mm, and the specification of viscose is 3D×76mm. The weight percentage of mixing is 20% of polyester and 80% of viscose. After the raw material passes through the cotton feeding weighing machine, it is sent to the cotton blending curtain opener for opening, and the opened cotton flow enters the multi-compartment blending machine for mixing, and the mixed cotton flow is sent to the cotton opener for further processing. open loose. In the preparation stage before web formation, the fiber raw materials are loosened, and the fiber blocks are changed from large pieces to small pieces. At the same time, the fibers are evenly mixed to prepare for the fiber web formation.

[0048] (2) into a network

[0049] The cotton after opening and mixing flows through the conveying fan and the carding machine to produce a fiber web 1 with a certain...

Embodiment 2

[0055] Elastic nonwovens prepared by air-laid method:

[0056] The difference from Example 1 is that the short fiber forming is not card forming, but air forming.

Embodiment 3

[0058] Spunbonded composite elastic nonwovens:

[0059] The difference from Example 1 is that the surface of the fiber web 1 after carding and laying is compounded with a layer of spun-bonded nonwoven fabric, and then the fiber web 1 is stitch-bonded.

Abstract

The invention provides a manufacturing method of an elastic non-woven fabric. The method comprises the following steps of 1, formation of a net, wherein a fiber raw material is subjected to processesof loosening, mixing, carding and net laying to form the fiber net of a network structure; 2, knitting of the fiber net, wherein a plurality of composite filaments are introduced into the fiber net made in step 1, the composite filaments repeatedly penetrate through the fiber net and form thread rings on the front and back faces of the fiber net, and the thread rings are mutually encircled according to a stitching rule of knitting textures on the front face of the fiber net; 3, post-treatment, wherein the fiber net made in step 2 is subjected to heat treatment. A thread ring structure formed by the composite filaments is utilized, so that the non-woven fabric has better ductility. Since the thread rings have the deformation ability in the longitudinal and transverse directions, the elasticnon-woven fabric has elasticity not only in the transverse direction but also in the longitudinal direction, the elasticity of the elastic non-woven fabric is not in one direction, and the disadvantage of easily forming the elasticity in one direction by means of a conventional elastic non-woven fabric preparation method is overcome.

Description

technical field [0001] The invention belongs to the field of production and manufacture of nonwoven fabrics, and in particular relates to a method for manufacturing elastic nonwoven fabrics, elastic nonwoven fabrics and elastic products. Background technique [0002] Non-woven fabric is a kind of textile staple fiber or filament is oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. It has the characteristics of multidisciplinary technology. In recent years, non-woven fabrics The application fields of woven fabrics continue to expand, and the development in the textile field is very rapid. It is considered to be a new economic growth point for the future development of the textile industry. Due to the good ductility of elastic nonwovens, they can be widely used in clothing, home textiles, medical and health materials, etc., and have received attention from various research units and enterprises. The ...
